Epigenetics
The depth of DNA and our genetic makeup can blow your mind. To consider that every human being can have the same foundation of genes, can make you wonder why do we all have different characteristics, traits and health issues. That all boils down to epigenetics, which are the markers in your genes that turn on or off, relatively like a light switch. It’s so compound that it has the ability to trigger certain things and change them within our bodies and they may not affect you at the time or even down the road but certain defects can be passed down to generations. Epigenetics is not set in stone; they are formulated to work depending on your surroundings, habits, foods, emotions and etc. Nobody knows how to turn the right genes on or off but by the simplest little changes in your life you can evolve a better life for yourself and future generations.
More studies had been done within mice, Agouti mice preferably. In this study they used to identical mice, except one was yellow and chubby while the other one was dark brown and thin. Both mice shared a particular Agouti gene, this gene was often turned on in the yellow mouse more frequently then the dark brown. So the reason for the weight gain and over eating in the yellow mouse was that the receptors that tells our brain that we are full, was blocked so the mouse had no self-control. When certain receptors are unresponsive it’s from a chemical tag called methyl molecule, which is composed of carbon and hydrogen which shuts the agouti gene off. So if the proteins hug DNA very tightly it hides from the cells and cannot be utilized within the epigenome. Epigenome tells the body when to work and how to work, so without control it changes.

Some more research has been done over Angelmans syndrome and Prader-Willi syndrome, which are to syndromes caused by the deletion of a gene in the15th chromosome with other genetic impairments. It ponders your mind to think why they are so different if the similarity in

    To understand implications that come with epigenetics, one must first understand epigenetics. So, what exactly is it? Simply put, epigenetics is the study of changes in gene expression not caused by alterations to the DNA sequence (Berger, Kouzarides, Shiekhattar, & Shilartifard, 2009). Recent studies have shown that the relation between DNA sequence and cell structure is not 1:1, that is to say that what you see in a creature’s DNA does not fully represent what the creature will be like (Berger, Kouzarides, Shiekhattar, & Shilartifard, 2009). Scientists have discovered that there are factors outside DNA structure that influence which parts of a DNA strand will be read and which will not. These factors can be further influenced by experiences within a creature’s lifetime (Berger, Kouzarides, Shiekhattar, & Shilartifard, 2009). This means that what humans do during their lifetime actually has an impact on their genetic code, and consequently, on the genetic code of their offspring. A common method used to explain the epigenetic phenomena is the light switch analogy: we as human beings make decisions and are subject to different events in our lifetime, these events and decisions effect our genetic code by…

    Paper on Epigenetics

    Epigenetics is a field where advances are being made daily. Epigenetics is defined as “heritable changes in gene expression that occur without a change in DNA sequence,” as stated by Dr. Alan Wolffe. A way in which we can understand this definition is by taking the analogy of a card game. The cards, the DNA sequence, have been dealt and will not change, however we need to understand how to play the cards, the rules, which is epigenetics. The guidelines can vary and completely change the way the card game is played and who comes out on top. The rules that are studied and understood through this research paper are those of DNA methylation and chromatin. These changes can produce large variations in the gene expression of cells while maintaining the same DNA sequence.…

    Ghost in Your Genes

    Genetic inheritance was thought to have involve the transmission of DNA from one generation to the next affected by occasional mutations in the DNA itself. They found out that the human genome was less complex and had less genes then even less complex organisms such as plants. The human genome, only containing about 30,000 genes, now lead scientists to believe that other factors allow genes to be switched on and off in response to the environment. Professor Pembrey was drawn to two genetic diseases due to families exhibiting unconventional genetic inheritance patterns. The two diseases were Angelman syndrome, which displays clinical symptoms of jerky movements, little or no speech and a very happy personality, and Prader-Willi syndrome, in which patients are found to be very floppy in infancy and develop an insatiable appetite associated with obesity in later life. He found out that these two diseases were caused by the same genetic alteration. There was a small deletion on chromosome 15. The parent from whom the mutation was inherited determined which disease the patient would get. If it was inherited from the mother the child would have Angelman syndrome and if it was inherited from the father the child would have Prader-Willi syndrome. This suggested that the chromosome knew its origin and must had been tagged or imprinted in some way. This was known as genomic imprinting. During sperm and egg production(meiosis), a chemical change results in the same DNA sequence on each chromosome having different functional properties. These events can lead to a particular gene being turned on or off. This is what epigenetics is based of. Professor Reik noticed that when a mouse embryo was placed in a culture dish some of genes would be switched off and wondered whether this could also be true for human embryos during in vitro fertilization or IVF. Using the disease, Beckwith-Wiedeman syndrome, Reik discovered that Beckwith-Wiedeman syndrome occurs…

    Obesity researches on overeating have been done on animals to test out the causes on eating too much. Researchers found that the animals that were fed tasty foods produced a chemical response in their brain. Beil quotes from Sarah Leibowitz who talks about the effects of palatable foods. “ ‘The more you eat, the more you want’ “(2). In the experiments that the researchers did on animals they also found out that the brain seems to attract us to high-calorie and low-nutrient foods. Beil also quotes from Mark Gold who discussed about tobacco addicts that led to obesity. “…eating may satisfy the same brain cravings that drive a person to addictive tobacco, alcohol, and drug use.”(2). Although the researches…

    The field of epigenetics is “the study of heritable changes in gene activity which are not caused by changes in the DNA sequence” (“Wikipedia”; n.d.). One can adopt a healthy lifestyle to change the impact of the genes inherited by an offspring. Ornish states that changing eating habits, loving more, and getting more exercise can cause a large increase in brain cells. (“ted.com/speakers”; n.d.) These changes could also impact the number of disease provoking genes that one will pass on to an offspring.…

    As it turns out, there may be more to inheritance than just DNA sequence. Epigenetics also could play a role. Epigenetics can dictate which genes in an organism are turned on and off and because of this, an organism can have several changes in their gene expression without any changes to their actual DNA sequencing. This information can persist within an individual because the epigenetic markings get copied along with the DNA when cells reproduce. As evidence accumulates, it is speculated that epigenetics could have played a role in the dramatic increase of illness in recent time.…

    In recent years it has become apparent that the environment and underlying mechanisms affect gene expression and the genome outside of the central dogma of biology. It has been found that many epigenetic mechanisms are involved in the regulation and expression of genes such as DNA methylation and chromatin remodeling. These epigenetic mechanisms are believed to be a contributing factor to pathological diseases such as Diabetes type II. An understanding of the epigenome of diabetes patients may help to elucidate otherwise hidden causes of this disease. Critical to the understanding of more complex mechanisms of inheritance we must first have a fundamental understanding of mitosis. Since 1996, as a newly assistant professor of biology, I started to integrate the African Diaspora into teaching the cell…

    One may argue that obesity is a disease because, like any other disease, it can interfere with the body not functioning properly. An excess amount of fat tissues will cause the overproduction of bodily molecules and mediators which contribute to abnormal regulation of food consumption and energy levels (American Medical Association). As being a problem with genetics, Albert J. Stunkard, MD states that studies have proven that inheriting obesity is…

    For the last few decades, and as long as many adults can remember, the view of gene inheritance has been written in the four letter language of DNA. Genetic mutations and re-combinations have driven most descriptions of how phenotypic traits are handed down from one generation to the next (The American Association for the Advancement of Science). Researchers and physicians attempted to untangle and discover the clues that suggested gene function could be altered by more than just changes in sequence (Weinhold, 2006). This research paper will discuss what epigenetics are, processes that are responsible for the different gene expressions in epigenetics, factors affecting epigenetic changes, and studies into epigenetics.…

    ONE of biology’s hottest topics is epigenetics. The term itself covers a multitude of sins. Strictly speaking, it refers to the regulation of gene expression by the chemical modification of DNA, or of the histone proteins in which DNA is usually wrapped. This modification is either the addition of methyl groups (a carbon atom and three hydrogens) to the DNA or of acetyl groups (two carbons, three hydrogens and an oxygen) to the histones. Methylation switches genes off. Acetylation switches them on. Since, in a multicellular organism, different cells need different genes to be active, such regulation is vital.…

    Genes are the reason why everyone has a unique identity. They control everything from hair and eye color, to dexterity and voice timbre. When a baby is conceived, these genes from the parents combine and come together to form a new formation of genes and DNA. So what happens if something goes wrong? If something does go wrong, it results in a genetic disease. For example, if someone is affected by an autosomal dominant disorder, they have a 50 percent chance of passing the mutated gene to their child. (2)…
